Functional Coating

Functional coatings are system solutions for mechanically stressed fastening elements, such as screws and nuts.
These coating types are applied using different application procedures. Depending on the coating, they can assume a locking, securing (captive) or holding, sealing function.

precote® – Adhesive coating

precote® Micro Encapsulated is a pre-applied locking adhesive. During installation, the pressure between the mating thread flanks will burst the microcapsules The adhesive and curing agent contained in the capsules are released and the adhesive cures.

• Locking effect according to DIN267 Part 27
• For nearly all materials and surfaces
• Fast hardening
• One-time use only
• Resistant to oils, greases, hydraulic fluids and liquid coolantsetc.
• Shelf life up to 4 years

TufLok® - Thread locking patch

TufLok® is reliable for thread locking and thread sealing fastened joints. Parts of the threads are given a coating of highly-elastic, abrasion-resistant polyamide. This fills in any axial play between the screw and the internal thread. It creates a dense, vibration-resistant connection.

• Securing (captive) function
• For nearly all materials
• No hardening time - can be stressed immediately
• Can be reused several times
• Resistant to alcohol, oil, fuel and most thinners
• Can be stored for an unlimited period of time

Nyplas® - Under-head coating

Nyplas® is a plastic coating (modified plastisol) for application on screws or other threaded components applied directly under the head, the flange or on the run-out of the thread. No manually applied washers, seals or O-rings required.

• Sealing/noise insulation immediately after screwing the parts together
• Coating on nearly all metal materials
• Depending on exposure to loads, coating can be reused several times
• Very good sealing properties
• O-rings, washers, etc. are no longer required
• Long service life, no shrinking or desiccation

Nyseal® - Under-head coating

Nyseal® is a plastic coating (polyolefin) for application on screws or other threaded components applied directly under the head, the flange or on the run-out of the thread. No manually applied washers, seals or O-rings required.

• Excellent sealing effect
• Coating on nearly all metal materials
• Depending on exposure to loads, coating can be reused several times
• Prevents contact corrosion under the screw head
• No additional washers or seals required
• High resistance to chemicals and oils

Nystay® - Fixing coating

Nystay® is a plastic precoating (polyolefin-based) which is applied directly to the shaft or the thread of fastening elements to help keep them in place during transport or assembly in their respective application or assembly group.

• Holding function
• Coating on nearly all metal materials
• Can be reused
• Non-toxic and environmentally friendly
• Reduces assembly time for final user
• Can be positioned anywhere on the shaft or thread of a fastening element
